Side measurement
Use the procedure below to measure position and angle by detecting the edges of the sides of a rectangular or
square object to measure. Set at least two of the measurement points so as to measure the same side. Use the
Edge Position processing item for edge measurement. For each measurement point, the Edge Position
processing item must be registered and used in the measurement flow. The movement amount may not be
calculated correctly if you use a processing item other than the Edge Position processing item.

Description
Used to set the number of locations to measure in the four
sides.
Set the measurement axis.
The measurement axis must be set to the actual coordinate
axis that is parallel to the direction of the measurement
region of the Edge Position processing item used for
measurement.
Set the X coordinate of the reference position.
Set the Y coordinate of the reference position.
Set the X coordinate of the measurement position.
Set the Y coordinate of the measurement position.
Description
Used to set the measurement axis used for angle
calculation.
This setting item is enabled when [2 points setting] is
specified for the method.
Set the method for angle specification.
• 2 points setting:
A method in which the measurement axis used for angle
calculation is set by specifying two points on the same
side.
• Calculation setting:
A method in which the reference angle and
measurement angle are each set by a calculation
expression.
